Frequently Asked Questions

What does the HTML Formatter change?

It adds consistent indentation and line breaks to make the document structure easier to read without intentionally changing the rendered page.

FAQ

Are script and style blocks preserved?

Yes. Their contents should be preserved and may optionally be formatted using the JavaScript and CSS formatter engines.

FAQ

Can formatting change whitespace on the page?

Whitespace can matter inside pre, textarea, script, style, and some inline content. The formatter should preserve sensitive content and avoid unsafe whitespace changes.

FAQ

Is my HTML uploaded?

No. HTML formatting runs locally in your browser.
